3 Claims.

This invention relates to an improved Woodworking plane. H V

In a conventional woodworking plane used by carpenters the plane bottomis formed with a transverse slot through which the cutting bladeextends, and it frequently happens in the planing of wood that theshavings clog up in the slot and impair the normal use of the plane. Itis, therefore, an object of this invention to provide in combinationwith a woodworking plane, means whereby any clogging chips or shavingsmay be instantly released.

Another object of this invention is to provide in a woodworking plane aspring-pressed plate disposed forwardly of the cutting blade with anoperating lever extending forwardly and about the front knob so that theplate may be raised to released position when any chips or shavings clogup the clearance slot.

With the above and other objects in view, my invention consists inthearrangement, combination and details of construction disclosed in thedrawings and specifications, and then more particularly pointed out inthe appended claims.

In the drawings:

Figure l is a detailed side elevation of a Woodworking plane constructedaccording to an embodiment of this invention.

Figure 2 is a fragmentary sectional view taken on the line 2-2 of Figure1.

Figure 3 is a sectional view taken on the line 33 of Figure 2.

Figure 4 is a fragmentary sectional view taken on the line 4-4 of Figure3.

Figure 5 is a perspective view of the chip releasing device.

Referring to the drawing, the numeral III designates generally awoodworking plane of conventional construction which has a cutting bladeI I and a rear upstanding handle I2 secured to a bottom I3. A forwardhandle or knob I4 is secured to the forward end of the bottom I3, andthe bottom I3 has disposed on the opposite longitudinal edges thereofupstanding side walls I5.

In conventional woodworking planes under certain conditions of the woodthe chips or shavings cling to the keen edge I 6' of the blade I I andclog up the clearance space I! which is formed transversely across thebottom I3.

In order to provide a means whereby any chips or shavings which may clogthe clearance space H, I have provided a vertically movable springpressed plate I8 which is disposed in the transverse slot or openingI'I.

Preferably the transverse slot or opening I! is widened to a substantialdegree forwardly of the keen edge It of blade II so that the plate I8may be movably disposed forwardly of the blade II. The plate I8 hasextending upwardly or right angularly from theopposite ends thereof apair of side members I9 which are formed with vertically disposedopenings 2t. I e The inner sides of the side walls I5 have securedthereto vertically disposed guide members 2I which loosely engagethrough the openings 28 so that the plate I8 with the upstanding ends orsides I9 may be vertically moved as will be hereinafter described. Whenthe plate I8 is in its lowermost and normal position with the lowersurface thereof flush with the lower surface of the bottom I 3 theconnecting member 22 which extends across the upper end of the opening20 will be disposed in abutting relation to the upper end of a guidemember 2I.

The U-shaped member which forms the plate I 8 and the upstanding slidemembers I9 is adapted to be movedupwardly to a released position bymeans of a releasing lever 23 which is rockably mounted on an upstandingpost 24 secured to the upper side of the bottom I3. The rear end of thelever 23 is reduced as indicated at 25, and the reduced end 25 looselyengages in an opening 2d formed in an upstanding lug 21 carried by theupper side of the plate I8.

The lever 23 extends forwardly from the supporting post 24 and is benton a curvature as indicated at 28 so as to engage about the knob I4, andto terminate at its forward end adjacent the forward end of the bottomI3. The plate I8 is normally urged downwardly to a normal lower positionby means of a pair of spring arms 29 which extend from a loop 30 whichis disposed beneath the knob I4.

The spring arms 29 constantly urge the plate It downwardly to the limitpermitted by the guides 2I. As shown in Figure 5 the opposite ends ofthe plate I8 are formed with cutouts or inwardly projecting slots 3|which are of a depth such that the plate I8 with the slide members I9may be vertically raised to remove the plate I8 from the plane forrepair of the device or for other purposes. The plate I8 with the slidemembers I9 may be removed by withdrawing the pivot pin 35 on which thelever 23 is rockably mounted and then removing the lever 23 and alsoremoving the spring members 29 by taking oil the knob I4.
